>> keep with the theory that it was a deliberate act you have to assume everybody on the plane is a suspect, passengers and crew, meaning they are trying to determine who may have had a motive to comandeer the plane.
>> reporter: as the search for flight 370 continues, malaysian officials are now looking at how the plane disappeared and who may be involved, including the crew. the flight's captain, in his 50s, highly experienced. he had logged 18,000 flight hours, his co-pilot, hamid, 27, relatively new with 2800 flight hours. both are being investigated. so is everyone on board. the key questions, who else on board could fly a triple 7 and who may have had a motive to take the aircraft and for what purpose. and if the plane was hijacked, where was it going? during the crucial hours of the plane, there could have been a breach of security.
>> if there was a real takeover, that would be the time where the crew members would be moving in and out to serve the drinks.
>> reporter: there were prayers for flight 370 today at the co-pilot's local mosque. friends here call him a quiet, respectful man, living with his parents in this middle class home. less is known about the pilots seem here at home improvement videos. he has a flight simulator at home. a man dedicated to flying. but malaysian officials are not telling us much more than that. so the wait for answers continues. so painful for family and friends of those on board. here at the airport they fill this wall with prayers and messages of hope for loved ones. they may never see them again. keir simmons .
>>> and we now want to bring in greg fife, a senior safety director and pilot. let's put to the side for a moment the question of who was flying the airplane. we heard in reports they're looking at two possible course changes, one to the north, one to the south. if you're trying to escape de detection, what is the more likely route?
>> lester, the more likely route is a southern route , there is no peninsula there, it is a vast, vast ocean, going almost as far down as the south pole .
>> and in fact we look at the graphic there pointing off the coast of australia , should they be searching in that part of the world? does the search area become that big?
>> i think so they have to put assets there now since they have a north and south track. i would be looking primarily in the south track. and in fact with australia being down there i may even request basically help from australia to assist in the search of that part of the ocean.
>> you know, i said earlier we've gone past the far fetched area of this. everything is really on the table, and whoever took it may have wanted to land it somewhere. if you take the southern route there is really no place to go.
>> there is no place, it is open ocean , you can land it in the water. but if you're going that direction and your intent is to basically just do something bad to the aircraft. that is the place to do it because if that airplane even breaks up and sinks that is a vast part of the ocean and world. you may never ever find the main wreckage, maybe you will find floating debris at some point but that is a place to get rid of an airplane.
